RELATED APPLICATIONS

This application is a continuation of U.S. application Ser. No. 13/470,032, filed May 11, 2012, which in turn is a continuation of U.S. application Ser. No. 10/791,156, filed Mar. 1, 2004, which claims priority to U.S. Provisional Application No. 60/520,173, filed on Nov. 14, 2003, the disclosures of which are incorporated herein by reference in their entirety.

FIELD OF THE INVENTION

The present invention relates generally to the field of e-commerce and, more specifically, to integrating third party shopping cart applications with an online payment service.

BACKGROUND OF THE INVENTION

The Internet has become the world's market place. Merchants are increasingly selling products and services via various online commerce facilities such as merchant web sites, online auctions, etc. On merchant web sites, products are typically sold using the “shopping cart” model that allows a customer to select an item from an electronic catalog and then metaphorically adds the selected item to a shopping cart. When the customer is done selecting items, the customer requests that the items in the shopping cart be “checked out”. At this point, a payment transaction is initiated, and the purchaser is asked to provide billing information such as a credit card number and other confidential information. Typically, merchants use customized shopping cart applications for providing a shopping cart flow and an independent online payment service (e.g., PayPal®) for handling payment transactions.

A large number of merchants offer their products via various online marketplaces, which often support a number of price-setting mechanisms (e.g., auctions). Different auction management tools (AMTs) have been developed to assist sellers in managing their items posted on various online auctions. AMTs usually send notifications to winning bidders. A winning bidder can then access the checkout flow using a link in the winning bidder notification and proceed with the payment. Typically, AMTs allow their users to make payments via an independent online payment service (e.g., PayPal®) that is trusted by the users for its secure, fast and easy-to-use operation.

SUMMARY OF THE INVENTION

According to one aspect of the present invention, detailed information concerning items placed by a user in a virtual shopping cart hosted by a merchant web site is received from a third party shopping cart application. The detailed information is sent by the third party shopping cart application in response to a user request to proceed with a payment for the items. Once the detailed information is received, the user is presented with one or more user interfaces facilitating processing of the payment. The user interfaces allow the user to view the content of the virtual shopping cart.

DETAILED DESCRIPTION

A method and system for integrating third party shopping cart applications with an online payment service are described. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the present invention. It will be evident, however, to one skilled in the art that the present invention may be practiced without these specific details.

Third Party Shopping Carts

FIG. 1 is a block diagram of one embodiment of a system 100 for processing online payment transactions initiated via merchant web sites. The system 100 includes multiple client computers (clients 1 through N) 102 coupled to multiple merchant servers (servers 1 through N) 112 and an online payment service 110 via a communications network 106, including a wide area network such as the Internet. Other examples of the communications network 106 may include a local area network (LAN), a wireless network (e.g., a cellular network), or the Plain Old Telephone Service (POTS) network.

The client 102 includes a client program 104, such as a browser (e.g., the Internet Explorer distributed by Microsoft Corp. of Redmond, Wash.) that executes on the client 102 and accesses the merchant server 108 and the online payment service 110.

The merchant server 108 supports a merchant web site that can be a retailer or wholesaler web site visited by various buyers including the users of the clients 102. The merchant web site uses a third party shopping cart application 112 that places items, selected by a buyer via the merchant web site, in a virtual shopping cart. A third shopping cart application 112 is an application external to the online payment service 110 that is developed by an external developer/company to allow a merchant or another third party to host a shopping cart on its web site. The shopping cart hosted by a merchant or any other third party is referred to herein as a third party shopping cart.

The merchant servers 108 are coupled to the online payment service 110 via the communications network 106. The online payment service 110 facilitates processing of online payment transactions between buyers of the merchant web sites 108 and the merchants. In one embodiment, the online payment service 110 includes interfaces to external processors to process payment transactions of corresponding types. In another embodiment, the online payment service 110 includes an internal payment processing system.

In one embodiment, the online payment service 110 is invoked by the third party shopping cart application 112 each time a buyer submits a request to proceed with the payment for items placed in a shopping cart hosted by a merchant web site. The buyer request may be submitted when the buyer clicks the checkout button on the merchant web site or performs some other predefined operation. Once the online payment service 110 is invoked, it presents to the buyer a set of user interfaces (UIs) that facilitate the processing of the payment while allowing the buyer to view the contents of the shopping cart for which the payment is being made.

In one embodiment, the online payment service 110 includes a third party shopping cart interface 114, a payment processor 116, a UI module 115, and a database 120. The third party shopping cart interface 114 is responsible for receiving, from the third party shopping cart application 112, detailed information about the items placed by the buyer in the shopping cart hosted by the merchant website and storing the detailed information in the database 120. The detailed information may include, for each item in the shopping cart, the item name, the item number, the item price, the item quantity, and various other data.

The payment processor 116 is responsible for collecting the buyer's personal information via UIs generated by the UI module 115, facilitating the processing of the buyer's payment for the items in the shopping cart, and informing the buyer that the payment has been sent to the merchant. The UIs presented to the buyer allow the buyer to view the contents of the shopping cart while the buyer's payment is being processed. Once the payment transaction is completed, it is reflected in the transaction history maintained by the online payment service 110 for each of the buyer and the merchant. When the buyer or the seller accesses his or her transaction history, this payment transaction appears as a standard payment transaction initiated via the online payment service 100.

Thus, embodiments of the present invention enable complete integration of the third party shopping cart applications 112 with the online payment service 110. As a result, merchants can seamlessly combine on their web sites customized shopping car applications, which provide additional means for promoting merchants' products, with an independent online payment service that is widely used and trusted by many users.

FIG. 2 is a flow diagram of one embodiment of a method 200 for processing a payment transaction initiated by the third party shopping cart application 112. The method 200 may be performed by processing logic, which may comprise hardware, software, or a combination of both. Processing logic resides in the online payment service 110.

Referring to FIG. 2, the method 200 begins with the third party shopping cart interface 114 receiving from the third party shopping cart application 112 detailed information on items placed by a user in a virtual shopping cart hosted by the merchant web site (processing block 202). The third party shopping cart application 112 sends the detailed information in response to a user request to proceed with the payment for the items in the virtual shopping cart. The user request may be submitted when the user clicks the checkout button on the merchant web site or performs some other predefined operation.

At processing block 204, the third party shopping cart interface 114 stores the detailed information in the database 120. The detailed information may include, for each item, the item name, the item number, the item price, the item quantity, etc.

At processing block 206, the payment processor 116 communicates to the user via the communications network 106 a set of UIs that facilitate processing of the user payment and allow the user to view the contents of the virtual shopping cart.

In one embodiment, all payment transactions initiated via merchant web sites are marked using a designated flag. The number of times the flag is passed through, and the dollar volume, are stored to monitor the usage of the integrated third party shopping carts. In one embodiment, a system administrator may request to view all payment transactions initiated via merchant web sites. Upon receiving a request from an administrator, the online payment service 110 presents to the administrator an administrator transaction details UI that lists all payment transactions initiated via merchant web sites as third party shopping cart payments and includes a table with third party shopping cart contents. The administrator can also request a report on the number and dollar volume of transactions that involve third party shopping carts.

FIG. 3 illustrates an exemplary flow of UIs presented to a user of a merchant web site, according to one embodiment of the present invention. Initially, a merchant web site 304 communicates to a user a merchant web site UI 308 that allows the user to view the items offered by the merchant. The user can order any of these items by clicking an associated “add to cart” button. Once the user is done with selecting the items, a third party shopping cart application running on the merchant web site 304 presents to the user a third party shopping cart UI 310 that display the contents of the shopping cart and allows the user to request a checkout of the selected items. When the user requests the checkout (e.g., by clicking the checkout button), a transition to the online payment service 306 is made.

During the transition, the online payment service 306 receives and stores information identifying the content of the virtual shopping cart. This information may include, for example, item names, item numbers, item prices, quantities, option data (option names and values) for each item, etc. In one embodiment, this information may result from user purchases via a single merchant web site. Alternatively, this information may result from user purchases via multiple merchant web sites associated with a single receiving account (e.g., a ticket company allowing a user to buy tickets via web sites of different ticket holders).

Upon the transition, the online payment service 306 enables the user to review the shopping cart contents on various screens generated by the online payment service 306. In particular, once the user requests the checkout, the online payment service 306 presents a login UI 312 that asks the user to sign-in (if the user is new to the online payment service 306) or login (if the user is an existing user of the online payment service 306), and allows the user to view the content of the shopping cart (e.g., by displaying the content of the shopping cart or including a link to a screen displaying the content of the shopping cart). Once the user provides the requested information, the online payment service 306 presents to the user a confirmation UI 314 that displays the details of the payment transaction and asks the user to confirm the payment. The confirmation UI 314 also allows the user to view the content of the shopping cart (e.g., by displaying the content of the shopping cart or including a link to a screen displaying the content of the shopping cart). If the user confirms the payment, the online payment service 306 presents to the user a done UI 316 informing the user that the payment has been sent to the merchant. After that, the user may either be returned to the merchant's website 304 or be presented with an account overview UI 318 that shows this payment transaction as part of the user's transaction history. The account overview UI 318 allows the user to view the content of the shopping cart to which the payment transaction belongs (e.g., by displaying the content of the shopping cart or including a link to a screen displaying the content of the shopping cart).

AMT SHOPPING CARTS

FIG. 9 is a block diagram of one embodiment of a system 900 for processing online payment transactions initiated via auction management tools (AMTs). The system 900 includes multiple client computers (clients 1 through N) 902, multiple AMT systems (AMT systems 1 through N) 908, multiple online auction facilities (auction facilities 1 through N) 112, and an online payment service 110.

The client 902 includes a client program 904, such as a browser (e.g., the Internet Explorer distributed by Microsoft Corp. of Redmond, Wash.) that executes on the client 102 and accesses the AMT systems 908 via a communications network 906, including a wide area network such as the Internet. Other examples of the communications network 106 may include a local area network (LAN), a wireless network (e.g., a cellular network), or the Plain Old Telephone Service (POTS) network.

The AMT system 908 provides to vendors an online tool for managing their sales on various network-based commerce facilities (e.g., online auction facilities 912, retailer or wholesaler facilities, etc.) represented by commerce web sites visited by various buyers including the users of the clients 902. The AMT system 908 provides the shopping cart flow for items ordered from merchant web sites, auction facilities 912, or any other commerce facilities on which merchants' sales are managed by the AMT system 908. Once a buyer selects an item on a merchant web site or wins a bid at an auction facility 912, the AMT system 908 places a relevant item in a virtual shopping cart (referred to herein as an AMT shopping cart 909). [0043] The AMT systems 908 are coupled to the online payment service 910 via the communications network 906. The online payment service 910 facilitates online payment transactions between various users. In one embodiment, the online payment service 110 includes interfaces to external processors to process payment transactions of corresponding types. In another embodiment, the online payment service 110 includes an internal payment processing system.

In one embodiment, the online payment service 910 is invoked by the AMT system 908 each time the AMT system 908 receives an indication of the buyer's intent to proceed with the payment for the contents of the AMT shopping cart 909. The buyer request may be submitted when the buyer clicks a designated link or button (e.g., the link identifying the online payment service, the checkout button, the add to cart button, etc.) or performs some other predefined operation. Once the online payment service 910 is invoked, it presents to the buyer a set of user interfaces (UIs) that facilitate the processing of the payment while allowing the buyer to view the contents of the AMT shopping cart 909 for which the payment is being made. If the payment transaction completes successfully, the online payment service 910 identifies shopping cart items from auction facilities 912 and communicates with the auction facilities 912 via the communications network 906 to inform the auction facilities 912 about the payment.

Each auction facility 912 includes a transaction postback processor 914 that marks auction transactions pertaining to the shopping cart items as paid.

In one embodiment, the online payment service 910 includes an AMT interface 916, a payment processor 918, a UI module 922, and a database 920. The AMT interface 916 is responsible for receiving, from the AMT 908, detailed information about the items in the AMT shopping cart 909 and storing the detailed information in the database 920. The detailed information may include, for each item in the shopping cart, the item name, the item number, the item price, the item quantity, and various other data. In addition, for each item from the auction facilities 912, the detailed information may include, for example, the specifier of the auction facility 912, the buyer ID within the auction facility 912, the transaction number within the auction facility 912, etc.

The payment processor 918 is responsible for collecting the buyer's personal information via UIs generated by the UI module 922, facilitating the processing of the buyer's payment for the items in the shopping cart, and informing the buyer that the payment has been sent to the seller. The UIs presented to the buyer allow the buyer to view the contents of the shopping cart while the buyer's payment is being handled. Once the payment transaction is completed, it is reflected in the transaction history maintained by the online payment service 910 for each of the buyer and the seller. When the buyer or the seller accesses his or her transaction history, this payment transaction appears as a standard payment transaction initiated via the online payment service 100.

In one embodiment, the payment processor 918 is also responsible for identifying which auction facilities have items in the shopping cart and informing those auction facilities about the payment.

Thus, embodiments of the present invention enable complete integration of the AMTs 908 with the online payment service 910 and involved auction facilities 912, transferring transaction information between these different systems in real time and allowing users to access the transaction information in each of those systems in real time.

FIG. 10 is a flow diagram of one embodiment of a method 1000 for processing a payment transaction initiated by the AMT 908. The method 1000 may be performed by processing logic, which may comprise hardware, software, or a combination of both. Processing logic resides in the online payment service 910.

Referring to FIG. 10, the method 1000 begins with the AMT interface 916 receiving from the AMT system 908 detailed information on items purchased by a user from one or more network-based commerce facilities (processing block 1002). The items purchased by the user are placed by the AMT system 908 in the AMT shopping cart 909. AMT system 908 sends the detailed information on the items to the online payment service 910 in response to receiving an indication of the user intent to proceed with the payment for the items in the virtual shopping cart. The indication of the user intent may be received when the user clicks a designated button or link on the AMT web site (e.g., the link identifying the online payment service 910, the checkout button, the add-to-cart button, etc.) or performs some other predefined operation.

At processing block 1004, the AMT interface 916 stores the detailed information in the database 920. For each item purchased from a merchant web site, the detailed information may include, for example, the item name, the item number, the item price, the item quantity, etc. For each item purchased from an auction facility 912, the detailed information may include, for example, the specifier of the auction facility 912, the buyer ID within the auction facility 912, the transaction number within the auction facility 912, the item number within the auction facility 912, the item name, the item price, the item quantity, etc.

At processing block 1006, the payment processor 918 communicates to the user via the communications network 906 a set of UIs that facilitate processing of the user payment and allow the user to view the contents of the AMT shopping cart.

At decision box 1008, the payment processor 918 determines whether the payment transaction is successful. If not, the method 1000 ends. If so, the payment processor 918 determines whether any items in the AMT shopping cart are from an auction facility 912 (decision box 1010). If not, the method 1000 ends. If so, the payment processor 918 identifies involved auction facilities (processing block 1012) and sends relevant payment information to the involved auction facilities (processing block 1014). This payment information may include the buyer ID within the auction facility, the transaction number within the auction facility, the item number within the auction facility, the payment amount, the item price, the item quantity, etc. The auction facilities then use this payment information to mark the relevant auction transactions accordingly (e.g., as paid, payment pending, etc.).

In one embodiment, all payment transactions initiated via AMTs 908 are marked using a designated flag. The counter specifying the number of times the flag is passed through and the dollar volume are stored to monitor the usage of the integrated AMT shopping carts. In one embodiment, the counter and dollar volume are maintained for each auction facility 912 to allow the auction facility 912 to compare the dollar volume associated with transactions initiated via the AMTs with the dollar volume associated with transactions initiated directly via the auction facility 912.

In one embodiment, the system administrator may request to view all payment transactions initiated via AMT shopping carts. Upon receiving a request from an administrator, the online payment service 110 presents to the administrator an administrator transaction details UI that lists all payment transactions initiated via AMT shopping carts as AMT shopping cart payments and includes a table with AMT shopping cart contents. The administrator can also request a report on the number and dollar volume of transactions that involve AMT shopping carts.

FIG. 11 illustrates an exemplary flow of UIs presented to a user, according to one embodiment of the present invention. Initially, an AMT web site 304 communicates to a user an AMT shopping cart UI 310 that displays information concerning the contents of an AMT shopping cart. A user may access the AMT shopping cart via, for example, a link in a winning bidder notification sent to the user, a designated link or button on the AMT web site 304, a button or link next to an ordered item on a corresponding merchant web site or auction web site, etc.

When the user provides an indication of his or her intent to proceed with the payment for the contents of the AMT shopping cart (e.g., by clicking the checkout or add to cart button or a designated link), a transition to the online payment service 1106 is made. During the transition, the online payment service 1106 receives and stores information identifying the content of the AMT shopping cart. This information may include, for example, an auction specifier, an auction buyer ID, auction transaction IDs, auction item numbers, item names, item prices, quantities, etc. This information may result from user purchases from one or more merchant web sites and/or one or more auction facilities.

Upon the transition, the online payment service 1106 enables the user to review the shopping cart contents on various screens generated by the online payment service 1106. In particular, once the user requests the checkout, the online payment service 1106 presents a login UI 1112 that asks the user to sign-in (if the user is new to the online payment service 1106) or login (if the user is an existing user of the online payment service 1106) and allows the user to view the content of the shopping cart (e.g., by displaying the content of the shopping cart or including a link to a screen displaying the content of the shopping cart). Once the user provides the requested information, the online payment service 1106 presents to the user a confirmation UI 1114 that displays the details of the payment transaction and asks the user to confirm the payment. The confirmation UI 1114 also allows the user to view the content of the shopping cart (e.g., by displaying the content of the shopping cart or including a link to a screen displaying the content of the shopping cart). If the user confirms the payment, the online payment service 1106 presents to the user a done UI 1116 informing the user that the payment has been sent to the merchant. After that, the user is presented with a transaction details UI 1118 that shows the details of this payment transaction. The transaction details UI 1118 allows the user to view the content of the shopping cart to which the payment transaction belongs (e.g., by displaying the content of the shopping cart or including a link to a screen displaying the content of the shopping cart).

Further, the online payment service 1106 communicates payment information to the involved auction facilities. A seller can then see relevant auction transactions marked as paid on screens generated by corresponding auction facilities.

FIGS. 12-17 illustrate exemplary user interfaces (Ills) presented to a user by the online payment service 1106, according to one embodiment of the present invention.

FIG. 12 illustrates an exemplary login UI 1200 for an existing user. The login UI 1200 includes a link 1202 that allows the user to view the content of the AMT shopping cart.
